Regression
Yes
Two independent Particle systems appear to be using the exact same seed for randomisation
How to reproduce:
1. Open attached project
2. Open scene particles.unity
3. Play the scene
- Note how the coloured particles and the black particles appear to be moving in the exact same patterns
- This happens even if the particles aren't parented/childed to each other
- The particles in both separate systems should be moving in different ways
- Reproduced in Version 5.4.0b11 (323b0238353b), Version 5.4.0b6 (2c3d6b93e789)
- Not reproducible in Version 5.3.4p1 (e89f89413a91)

This is definitely still not fixed in 5.4.1 (5.4.2 download has been pulled).

Still seeing this issue in 5.4.1 even though it's claimed to be fixed. Different seeds produce the exact same pattern of particles. The workaround of manually randomizing the seed does nothing.
ps.randomSeed = (uint)Random.Range(0, int.MaxValue);
ps.Emit(10);

Does 'Workaround is possible' mean that there is a workaround? What is it? Giving the particle systems new seeds doesn't seem to make any difference.
